滚动画布广告控制装置设计

范文编号:ZD250 范文字数:10791,页数:27

摘 要
 本范文主要介绍一种由可编程序控制器（PLC）、红外传感器、电动机为主要器件构成的新型广告发布装置——滚动画布广告控制系统。这种新型滚动画布广告控制装置是将五幅画面连接起来装在露天灯箱中，画布用电动机拖动，可上下进行循环显示，信息量大，动态效果好，可以对多种商品进行介绍或宣传，在街头构成一道风景线的同时也适用于大商场中对商品信息以及销售情况进行介绍。画布可以定期更换，方便不同商品需要。
 在画布循环运行过程中，各个画布画面出现的时间都保持一致，展示一定的时间后再改变到下一序号的画面。PLC靠软件程序对5幅画面的运动进行控制，并克服了自动运行中会遇到的各种问题，保证画布按要求正确运行。此外，该控制装置还具有手动/自动切换、定时开/关机、断电保持及故障诊断并报警等功能。
关键词：滚动画布广告；可编程序控制器（PLC）；自动运行；故障报警

Abstract
 The thesis introduces one kind of the canvas rolling from the programmable controller (PLC) , infrared sensor , electric motor for new model advertisement that the main component composes announces a device advertisement control device mainly. That advertisement is equipped with this new model rolling canvas under the control of is in open-air lamp case with five tableaux link dress , canvas uses electric motor to drag moving , may carry out circulation display , amounts big , dynamic information effect about well, simultaneous being able to carry out the line introducing or propagating the scenery composing one, in street on diversified commodities introduces that in being unable to apply to market big to being in progress as well as merchandise news selling condition. Canvas is not bad change at the regular intervals , be unlike conveniently commodity need.
 Circulation work process is middle in canvas, each canvas tableau the time appearing all keeps the tableau changing again to time as soon as serial number after showing certain time consistently. And PLC is in progress to 5 tableaux motion by the software program under the control of, have overcome an automation running middle various problem that can come across , have ensured that canvas works according to demanding correctly. Besides, should control a device having hand movement/ the automation changes shut-down , interruption of power supply by all means , holds at the regular time/ to keep functions such as reaching the malfunction diagnose and giving an alarm.
Keywords: Canvas rolling advertisement; Programmable Logic Controller(PLC); The automation works; Malfunction give an alarm
